MSSQL 跨服器调用存储过程

• A库

• CREATE PROCEDURE [dbo].[A_P_Test]
  AS
  BEGIN
     SELECT * FROM dbo.A_LoadData
  END

• B库  在B中调用A库存储过程 注：是同一服务器调用。 

• CREATE PROCEDURE [dbo].[A_P_Test2]
  AS
  BEGIN
      declare @sql nvarchar(500);
      set @sql = N' exec AMACDB_TEST.dbo.A_P_Test ';
      exec  sp_executesql @sql
  END

• A，B两个数据库，不在同一台服务器实例， 在B库的存储过程中，调用A库的存储过程

      B库

     

CREATE PROCEDURE [dbo].[A_P_Test2]
AS
BEGIN
   declare @sql varchar(MAX);
   set @sql = N' exec OPENDATASOURCE(''SQLOLEDB'',''Data Source=192.168.120.13;User ID=sa;Password=sa'').AMACDB_TEST.dbo.A_P_Test ';
   exec  sp_executesql @sql
END

SQL Server blocked access to STATEMENT 'OpenRowset/OpenDatasource' of component 'Ad Hoc Distributed Queries'

because this component is turned off as part of the security configuration for this server.

A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure.

For more information about enabling 'Ad Hoc Distributed Queries',

see "Surface Area Configuration" in SQL Server Books Online.

解决方法如下：

exec sp_configure 'show advanced options',1
reconfigure
exec sp_configure 'Ad Hoc Distributed Queries',1
reconfigure
